On transversal S, value of x =120 On transversal T, value of y= 135 So answer is 255

Ans 2:

Class : Class 8
x=180-60=120(corresponding angles are equal) y= 180-45=135 (corresponding angles are equal) x+y=120+135=255

the LCM of 8,16 and 32 is 32 5/8=20/32 8/16=16/32 21/32=21/32 therefore, 16/32<20/32>21/32 also, 8/16<5/8>21/32 therefore 5/8 is between 8/16 and 21/32

Ans 2:

Class : Class 7
5/8=10/16=20/32...so option B is out (19/32 is less than 20/32) Option C is out (10/16 is is greater than 8/16) and for same reason option D is also out So answer is option A
